The balanced equation for the combustion of Hydrogen is: 2 H2 + O2 → 2H2O

How many moles of H2O will be formed from the complete reaction of 0.750 moles of O2?

0.375 mol
1.50 mol
2.67 mol
0.750 mol

1.5 moles H₂O

General Formulas and Concepts:

Chemistry - Stoichiometry

Explanation:

Step 1: Define

RxN:   2H₂ + O₂ → 2H₂O

Given:   0.750 moles O₂

Step 2: Stoich

= 1.5 moles H₂O

Step 3: Check

We are given 3 sig figs.

Since our answer is 2 sig figs, we don't need to round.

answer: e.   sour taste

explanation: acids are those substances which dissociates in water to give ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. acids are sour in taste. example: hcl

bases are those substances which dissociates in water to give ions or accepts ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. bases are bitter in taste. bases are slippery in nature.
